State Database Replicas and Trans Metadevices

Creating a trans metadevice (UFS logging) is an easy way to increase availability of UFS. Here's a tip that makes efficient use of slices when using trans metadevices:

• On new systems, create two to three small slices (8-10 Mbytes each) on each disk. Use these slices to hold not only state database replicas but also logging devices. As a general rule of thumb, as you add new disks to a system, use this method for configuring state database replicas and trans metadevices. That way, you can take care of two DiskSuite objects with one slice.

For more information on adding a state database replica or creating a trans metadevice, refer to Chapter 2, Creating DiskSuite Objects.
